jquery制作弹出层带遮罩效果，点击阴影部分层消失。
整体还是比较简单的。
HTML代码很简单
1 <a href="#" class="big-link" data-reveal-id="myModal" data-animation="fade">jquery点我弹出</a> 2 <div id="myModal" class="reveal-modal"> 3 <h1>jquery弹出层</h1> 4 <p>很不错的效果</p> 5 <a class="close-reveal-modal">×</a> 6 </div>
定义弹出层的样式
1 .reveal-modal-bg { position: fixed; height: 100%; width: 100%; z-index: 100; display: none; top: 0; left: 0; background:rgba(00, 00, 00, 0.8) } 2 3 .reveal-modal { visibility: hidden; top: 150px; left: 50%; margin-left: -300px; width: 520px; position: absolute; z-index: 101; padding: 30px 40px 34px; -moz-border-radius: 5px; -webkit-border-radius: 5px; border-radius: 5px; -moz-box-shadow: 0 0 10px rgba(0,0,0,.4); -webkit-box-shadow: 0 0 10px rgba(0,0,0,.4); -box-shadow: 0 0 10px rgba(0,0,0,.4); background-color: #FFF; } 4 5 .reveal-modal.small { width: 200px; margin-left: -140px;} 6 .reveal-modal.medium { width: 400px; margin-left: -240px;} 7 .reveal-modal.large { width: 600px; margin-left: -340px;} 8 .reveal-modal.xlarge { width: 800px; margin-left: -440px;} 9 10 .reveal-modal .close-reveal-modal { font-size: 22px; line-height: 0.5; position: absolute; top: 8px; right: 11px; color: #333; text-shadow: 0 -1px 1px rbga(0,0,0,.6); font-weight: bold; cursor: pointer; }
重点是js
引用jquery库是必不可少的。
<script type="text/javascript" src="jquery-1.4.4.min.js"></script>
最后是js
